Be it known that 1, JOHN HIGHAM, a citizen of the United States, residing at Los.

Ovens, of which the followingis a specifi-,

cation. 1 v t This invention relates to av foldable oven and an object thereof is to provide an oven which may be folded into a flat package so as to occupy a minimum space and which is especially applicable for use as a camp accessory and employed with camp stoves and the like. 7 v 1 Another object is to provide a foldable oven so constructed as to be securely and rigidly held in its open position against possibility of being accidently collapsed. i

A further object is to provide an oven of the above. charactercomprising few parts which. may be readily assembled so as to enable the oven being built at comparatively small cost. l a

Other objects will appear hereinafter. The invention isillustrated in the accompanying drawings, in which I Figure 1 is a perspective view .of the oven as seen in its open position.

Figure 2 is a pers ective view showing the manner of folding t e oven.

Figure 3 is a plan view.

Figure 4 is a view in transverse section as seen on the line 44 of Figure 3.

Figure 5 is a view in longitudinal section as seen on the line 55 of Fig. 3.

Figure 6 is a horizontal section and plan view as seen on the line 6-6 of Figure 1.

Figure 7 is a detail showing modification of the means for tying the front portion of the sides of the oven together.

Figure 8 is a detail in cross section showing modified form of the oven bottom construction.

More specifically, 9 indicates the oven top which is rectangular in form and formed with downwardly extending flanges 10 on its opposite side edges and along its rear edge and hingedly connected to the inner faces of the flanges 10 are side panels 1112 and a back panel 13 each of which panels are adapted to be folded inwardly to extend substantially parallel with the top panel 9 or to be disposed in an open position substantially at right angles to the top panel; the flanges 10 serving as abutments to limit the outward swinging movement of the panels 11-12 and 13 and to closethe joint formed at the hinged connection of the panels to the top panel when the oven is in its open position, as shown inFigure 1. V

The side panels 1112 are formed at their rear ends with inturned flanges 14 against the inner faces of which the back panel 13 may be swung and which flanges serve as abutments for the ends of the back panel and also act to close the joint between the .end panel and'the side panels'when in their open position, as particularly shown in Figure 6. i

As a means forfastening the side panels to the back panel in their open position to hold the side panels against spreading the side panels are formed with openings 15 adjacent the flanges 14 and hooks 16 are mounted in the inner face of the back panel and arranged to be detachably engaged with the side panels by passing their hooked ends through the opening 15.

Hinged on the forward edge of the top panel 9 is a door 17 which is adapted to be swung to lie against either side of the toppanel and to depend from the top panel and extend between the forward ends of the side panels when the oven is in its open position to close the oven or to be turned upwardly over the top of the oven to give access to the interior of the oven..

The oven is provided with a bottom wall 18 which may comprise a detachable panel adapted to slidably engage the side panels 11 and 12 and to seat upon inturned flanges 19 formed on the lower edges of the latter as shown in Figures 1 to 6 inclusive or may comprise a pair of panels 20 and 21 hinged at 22 on the lower edges of the side panels, as shown in Figure 8. I

Formed on the inner faces of the side panels are flanges 23 forming a seat for a demountable shelf 24 here shown as comprising side frame members 25 and 26 connected together by cross bars 27.

The outer ends of the side frame members 25 and 26 are formed with hooks 28 and 29 adapted to extend astride of and engage the forward edges of the side panels 11 and 12, as particularly shown in Figure 6, to hold the forward portions of the side panels against spreading; the shelf thus serving as a tie and co-operating with the hooks 16 on the back panel in holding the oven in its open position and which with the bracingeffect of theflanges 10 is overlapping the outer-faces =of the side panels serves to rigidly hold the oven in shape and insures against its being accidentlyi collapsed.

In some instances the tying togeth r of" ";,tion from entering the oven,

the forward portion of the side panels may be effected byforming the slide bottom panel With hooks 30, asshown inyFigure' '7,

which hooks are formed at the forward corners of the bottom plate and extendto the s'ide'thereof so as'tobe'engageable'avith the 1 forward edges of the side panels,
